In 1669, the year of the printing of the book, there were only two Dukes in England - Norfolk (created 1483); and Somerset (1547), and another two in Scotland - Hamilton (created 1643), and Buccleuch (1663). Up to the end of the seventeenth century, six more dukedoms were created in England, and one in Scotland. They were in England: Richmond (1675); Grafton (1675); Beaufort (1682); St. Albans (1684); Bedford (1694); and Devonshire (1694). In Scotland there was the Duke of Lennox (1675). Within this brief time span there are no dukes or duchesses who match the monogram. Monograms are notoriously difficult to decipher. Those represented in the stamp could be C C or S C.
